| Abstract: |
| Seven sampling points were collected from the eucalyptus forests in western Guangdong to study
the variability of soil nutrient content in eucalyptus plantation. The results showed that the total nitrogen, total
phosphorus, total potassium, and organic matter in the 7 sites of the eucalyptus plantation in western Guangdong
were all moderately variable, and the soil nutrient levels were significantly different. The level of total nitrogen
nutrients was in the middle low level, the level of total phosphorus nutrients was in a very low state, the total
potassium nutrients were in a medium state, and the organic nutrient levels were at a low level. There was a very
significant positive correlation between total nitrogen and organic matter, and there was a very significant negative
correlation between the total phosphorus and total potassium. |
